Time after time – circadian clocks through the lens of oscillator theory
FEBS Letters, EarlyView.Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

A relativistically covariant version of Bohm's quantum field theory for the scalar field
, 2004 We give a relativistically covariant, wave-functional formulation of Bohm's quantum field theory for the scalar field based on a general foliation of space-time by space-like hypersurfaces. The wave functional, which guides the evolution of the field, is

Uniformizable foliated projective structures along singular foliations
Mathematische ZeitschriftAbstract We consider holomorphic foliations by curves on compact complex manifolds, for which we investigate the existence of foliated projective structures (projective structures along the leaves varying holomorphically) that satisfy particular uniformizability properties.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS
FEBS Letters, EarlyView.We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Global Geometry of Bayesian Statistics
Entropy, 2020 In the previous work of the author, a non-trivial symmetry of the relative entropy in the information geometry of normal distributions was discovered. The same symmetry also appears in the symplectic/contact geometry of Hilbert modular cusps. Further, it

Top dimensional group of the basic intersection cohomology for singular riemannian foliations
, 2005 It is known that, for a regular riemannian foliation on a compact manifold, the properties of its basic cohomology (non-vanishing of the top-dimensional group and Poincar\'e Duality) and the tautness of the foliation are closely related.

Intein‐based modular chimeric antigen receptor platform for specific CD19/CD20 co‐targeting
Molecular Oncology, EarlyView.CARtein is a modular CAR platform that uses split inteins to splice antigen‐recognition modules onto a universal signaling backbone, enabling precise, scarless assembly without re‐engineering signaling domains. Deployed here against CD19 and CD20 in B‐cell malignancies, the design supports flexible multi‐antigen targeting to boost T‐cell activation and

Combinatorial volume preserving flows and taut foliations [PDF]
, 2000 A π₁-injective closed surface in an orientable 3-manifold with a tangentially smooth, transversely C⁰ taut foliation can be homotoped to an immersed surface which is either transverse to the foliation except at isolated saddle tangencies or mapped into a

Lifting a Weak Poisson Bracket to the Algebra of Forms
, 2016 We detail the construction of a weak Poisson bracket over a submanifold of a smooth manifold M with respect to a local foliation of this submanifold. Such a bracket satisfies a weak type Jacobi identity but may be viewed as a usual Poisson bracket on the

Planar polynomial foliations [PDF]
Proceedings of the American Mathematical Society, 1980 Let P ( x , y ) P(x,y) and Q ( x , y ) Q(x,y) be two real polynomials of degree ⩽ n \leqslant n with no common real zeros. The solution curves of the vector field
